Abstract: 409,558. Road - traffic signals on vehicles. EVANS, C. J., 99, London Road North, Lowestoft. March 23, 1933, No. 23585. Divided application. [Class 118 (ii).] Signalling lamps for use, prior to and during reverse movement, on a motor vehicle equipped with pre-selector gear change mechanism, are energized on closure of a switch arranged to be closed by the movement of an element, e.g. 39 of the gear actuating mechanism which is under the control of the cam shaft 34 of the preselector gear change mechanism. The switch 12 (not shown) maybe of the spring-controlled plunger type, the operating stud 13 of which is arranged adjacent to a member 39 associated with the reverse gear mechanism 36-49 which is pre-set by movement of the pre-selector cam-shaft 34, 35 so that movement thereof into the reverse gear engaging position causes closure of the switch. The operating stud 13 of the switch may be arranged adjacent the " reverse " actuating strut 39 which is under the control of the cam shaft 34 through a spring 37. Alternatively movement of a brake actuating thrust pad 41 of the gear box, which pad is moved by the strut 39, may cause depression of the operating stud 13. The circuit of the signalling lamp may be made independent of the ordinary lighting circuit switch on the vehicle.

Abstract: 941,477. Preventing explosions. W. JORDAN. July 3, 1961 [July 6, 1960], No. 23889/61. Heading A5A. [Also in Divisions A4 and F1] A travelling pumping station, e.g. for aircraft refuelling, has an engine 1 in a gas-tight housing 7, mounted with a fuel pump 6 on a common chassis 24, the housing being kept under internal over-pressure by means of a cooling air blower 10 operable either by hand or by the engine. An air-cooled 4-cylinder, 4-stroke I.C. engine 1 having an electrical starter 18 drives fuel pump 6 through clutches 3, 5, and a connecting-shaft 3a which passes through a stuffing-box 4 mounted in fire-resisting wall 23 of the gas-tight housing 7. The exhaust pipe 22 has a swivelling end-piece 22a terminating in a flame trap 22b, and is enclosed in a cooling air tube 22c. An air intake duct 8 is arranged to be folded or collapsed over the cover of the housing 7 for transportation. The capacity of blower 10 and the ratio between the cross-sections of intake 8 and outlet 20 are arranged so as to give a slight overpressure in housing 7. An instrument panel 17 carrying a starting and control mechanism 15, is mounted so that it is ventilated with housing 7. Prior to starting, cooling air is drawn into and used to ventilate gas-tight housing 7 by manually cranking handle 14 to drive blower 10 through shaft 12a and gears 12, 11. The bevel gears 13, 13a drive starting mechanism 15 and during normal running the blower 10 is driven from gear unit 2 through clutch or coupling 9.

Title: Electric switches
IPC: H01H33/14
Filed: 1924-10-09
Abstract: 241,378. British Thomson-Houston Co., Ltd., and Riggstory, L. Oct. 9, 1924. Heavy-current switches of the knifeblade type having multiple contact blades are arranged with each knife blade independently operable. In the selector switch shown in Figs 1 and 2 where a number of knife blades 19 are movable about a fixed pivot 21 between sets of contacts 14, 15 connected to duplicate bus-bars 11, 12 each blade is provided with an eyelet 23 into which the hooked end of an operating rod may be inserted. Each blade also carries a lateral projection 24 which engages and moves over with lost motion the adjacent blade. Thus in moving the blades over from the position shown in Fig. 6 the lower blade in its motion moves the adjacent blade to a position, Fig. 8, in which its eyelet is exposed so that the operating member may move it in turn and in doing so move the third blade sufficiently to expose its eyelet. Thus the blades are moved over one after the other to the alternative contact position.

Title: Improvements relating to apparatus for converting a number in binary reflected code into a conventional binary number
IPC: H03M7/16
Filed: 1960-07-08
Abstract: 877,705. Electric selective-signalling systems. COMPAGNIE FRANCAISE THOMSONHOUSTON. July 8, 1960 [July 9, 1959], No. 23967/60. Class 40 (1). A recording device for converting from monophylic binary to pure binary is characterized in that it employs magnetic cores. As described the monophylic binary bits are applied serially to an input winding ae, highest denominational bit first, and the pure binary bits appear serially, but one-bit period later, on a lead S. The logical operation of the circuit is that the first and highest denominational monophylic bit is unmodified and appears on the output lead S (after a bit-period delay). Subsequent monophylic bits are " added " (0+0 = 0, 0+1 = 1, 1+1 = 0) with the pure binary bit corresponding to the immediately preceding monophylic bit. The detailed operation of the circuit in converting monophylic 101 to pure 110 is summarized in the following table in which T 1  and T 2  are timing pulses which occur successively within a bit-period but after the arrival of the monophylic bits. The output pulses are produced at T 1  times.

Abstract: 670,803. Controlling motor vehicles. GHURYE, S. G. Sept. 20, 1949, No. 24203/49. [A Specification was laid open to inspection under Sect. 91 of the Acts, April 6, 1950]. Class 79 (v). In a common mechanical control system for the clutch and brakes of a motor vehicle, in which the common control pedal is movable to actuate the clutch independently of the brakes or to actuate the clutch and brakes in succession, the control pedal and a lever connected to the brakes are freely pivoted to a rod connected to the clutch, the control pedal has an arm arranged to act on a lever connected to the clutch rod so that initial movement of the control pedal causes clutch disengagement and causes another arm of the control pedal to move toward the brake lever and further movement of the control pedal causes a portion of the first arm to ride against the free end of the clutch lever without turning the latter to hold the clutch disengaged whilst the second arm applies the brakes shortly before the clutch is fully disengaged, so that on its return movement the control pedal brakes remain applied until the restoring force of the clutch returns the control lever to its initial position. As shown, the control pedal 1 having a counterweight 5 is rotatably mounted on the clutch rod 2 carried in bearings on bars 17 secured to the frame of the vehicle. The rod 2 is connected by an arm 22, link 23, arm 21 and a rod 8 to the lever 6 which is adapted to be engaged by a member 10 on the first arm of the pedal 1. Rotatably mounted on the rod 2 is the lever 7 which operates the brakes by an abutment 14 thereon connected to the piston of a hydraulic actuating system. When the pedal 1 is first depressed the clutch is disengaged through the member 10 engaging the lever 6 and progressive movement of the pedal causes actuation of the brakes by a cross-piece 13 on the lever 7 being engaged by the pedal 1. During the actuation of the brakes the arm 6 is not further moved due to engagement with an arcuate surface 11 on the member 10. A yieldable stop may be provided to indicate when the clutch has been disengaged. The pedal 1 may be provided in addition to the normal clutch and brake pedals.
